Distributed antenna systems for efficient wireless systems, 2011-01-01 - 2015-12-31
For distributed antenna systems, which consist of a central processing unit that performs joint processing of the signals from a very large number of base station/access point antennas, there is currently a severe lack of knowledge regarding many very fundamental issues. In this project, we aim for an interdisciplinary research effort where we will study hardware architectures and hardware limitations as well as theoretical limits of possible network performance. The project consists of two phases. In the first, we will develop an initial system design based on state-of-the-art knowledge, derive requirements on hardware and algorithms and create a test range for propagation channel studies. In the second phase, we will design and implement low cost RF heads and FPGA hardware, design algorithms based on propagation channel models from the first phase and ultimately evaluate the full system performance in our test range. The expected project outcomes are 1) network deployment guidelines for indoor and outdoor cellular and wireless systems when using distributed antenna systems; 2) suitable hardware architectures and designs for low cost distributed antenna systems; 3) low complex base band solutions for centralized processing; and 4) propagation models for distributed antenna systems or large arrays. |

VINNOVA Industrial Excellence Center - System Design on Silicon, 2008-01-01 - 2017-12-31
A key motivation for IXC SoS is to strengthen Swedish competitiveness in wireless communications through providing research at the international forefront in the area of system design on silicon. After its second year of operation IXC SoS has established itself as a competitive international research facility within the area of integrated circuit design. Cooperation with key industrial players gives the center a unique opportunity to address relevant research questions. The main focus of the center is to develop novel architectures and circuit solutions for terminals in the area of wireless communication. To achieve efficient solutions and provide application flexibility the hardware platform is developed jointly with the overall system specification. Therefore, the center has a close cooperation with researcher in adjacent fields, both in academia and industry. Several projects has been initiated in cooperation between the partners in for example the fields of transmitters with adaptive impedance matching, micro and mm-wave CMOS Circuits, all-digital PLL frequency synthesizers, high performance AD- converters, low-power digital circuits and reconfigurable computing. Furthermore the center activities connect to the emerging field of nano-electronics. The research achievements will be addressed in this annual report.
IXC SoS has a solid foundation and is an import resource in providing the possibility to have a long term research agenda. Furthermore, IXC SoS works as a key enabler in attracting additional research projects. Worth mentioning is the recently granted initiative within the Swedish government’s strategic research support ELLIIT, together with Linköping University, and the EU FP7 project DRAGON together with among others the IXC SoS partners Ericsson AB and Infineon.
